Here's a lighthearted cautionary warning for your Sunday morning -- your BMW may do a lot of things well, but that doesn't include floating! Check out this disastrously amusing video of a BMW owner treating his BMW as a boat.

BMW engines have good record of performing well on the water, but unfortunately the OP has chosen the BMW designed for dry land. Had he used the BMW VI, he would have been OK. The BMW VI was a 12-cylinder used in Dornier Wal flying boat.
